Exact replacement master cylinder for 2023 SideWinders and Thundercat. Also works on earlier models nicely.
Solid sturdy master cylinder. Replaced the OE unit on my '18 AC Mtn Cat. Much better trigger and overall size. Solid braking!
This is basically the same master cylinder cat will charge $100+ more for. I upgraded from an older style hayes master cylinder on a 18 m8000 mainly for the upgraded trigger but it's a lighter better master cylinder all around.
